摘要： A personal watercraft includes an inner lid attached in covering relation over a rear portion opening provided in a deck of the personal watercraft, in which a rear edge of the rear portion opening is pressed by a locking member disposed in a locking position thereof to assure the air-tightness of the inner lid, and a rear cover 48 is provided in covering relation over the inner lid. A projection is provided integrally on the locking member which allows attachment of the rear cover when the locking member is in the locked position, but blocks attachment of the rear cover by being sandwiched between the deck and the rear cover, when the locking member is at an unlocked position thereof. A torsion spring (biasing member) which biases the locking member toward the unlocked position is provided between the locking member and the deck. The attaching structure prevents the inner lid from being not attached inadvertently.

摘要： A personal watercraft deck structure includes a deck, a rear portion opening provided continuously to the rear of a seat underlying opening in the deck, and a bridge member is removably attached at a boundary between the seat underlying opening and the rear portion opening (or at the rear portion opening). A rear portion of a seat is supported by the bridge member, while the rear portion opening is operatively closed with a rear cover. When maintenance of an engine and other equipment disposed within the deck structure is to be performed, the bridge member may be removed. As a result, the seat underlying opening and the rear portion opening are connected to each other and fully exposed, and therefore, a large opening can be obtained for facilitating maintenance of the engine and other equipment.

摘要： A steering device for a personal watercraft includes a handle holder fitted to a watercraft body. A steering shaft passes through the handle holder, and a handle is fitted to the upper end of the steering shaft. The steering shaft is provided with a groove, and a holding member is provided in the handle holder and is fitted into the groove. Accordingly, movement of the steering shaft in the axial direction is restricted. A flange or the groove has a shape such that its width can be reduced. When the holding member is fitted by setting the width to a small size, and taking dimensional variations into account, the chattering between the flange or the groove and the holding member can be reduced. In view of this, the steering shaft is provided with the flange or the groove, and the holding member provided in the handle holder is fitted to the flange or the groove, so that movement of the steering shaft in the axial direction can be restrained. As a result, a steering device enhanced in feeling during operation can be realized.
摘要翻译：用于个人船舶的转向装置包括安装在船体上的把手座。转向轴通过把手保持架，手柄安装在转向轴的上端。转向轴设置有槽，并且保持构件设置在把手保持器中并且装配到槽中。因此，转向轴在轴向的移动受到限制。凸缘或凹槽具有能够减小其宽度的形状。当通过将宽度设定为小尺寸并考虑到尺寸变化来安装保持构件时，可以减小凸缘或凹槽与保持构件之间的颤动。鉴于此，转向轴设置有凸缘或槽，并且设置在把手保持架中的保持构件装配到凸缘或槽中，从而可以抑制转向轴在轴向方向上的移动。结果，可以实现在操作期间增强感觉的转向装置。

摘要： To provide an article storage structure for a small boat having a reduced number of components and being able to be assembled without much time and effort. The article storage structure for a small boat is constructed in such a manner that a storing box body is supported so as to be capable of being opened and closed in the vertical direction by swinging a lid by a front hinge. The front hinge includes a bearing bracket mounted on the lid. A round hole is formed on the bearing bracket. A notch is provided continuing into the round hole. A bifacial shaft has an outer diameter corresponding to the round hole and is formed with two faces each having a width corresponding to the width of the slit by notching. A leg portion is provided for fixing the bifacial shaft to the hull. A retaining member is provided for preventing the notch and the bifacial shaft from establishing an angular relation in which they can be attached and detached with each other when the notch is rotated about the bifacial shaft.
